Revelstoke Aquatic Centre Final Report

Site Analysis and Urban Design Concepts

Using the collected information, a graphic site analysis, urban design concepts and architectural concepts were prepared for the first open house. Important considerations included:

Geotechnical, structural and civil analysis
Mass and texture of adjacent structures
Set back and alignment on Campbell Ave
Zoning and development requirements
Adjacent intuitional uses scale and texture
Flood plain and fisheries requirements
Views and sun exposure
The existing building

Parking Analysis

A general approach was taken to review the parking and traffic issues associated with the proposed aquatic facility addition. On site observations were conducted to review the existing pavement markings, land use and adjacent street parking. The existing parking consists of 104 parking spaces as shown in the diagram below.

The parking requirements for the aquatic facility are determined according to Revelstoke Bay law Section 12 - OFF STREET PARKING, sentence 12.4 Required Off Street Parking, Institutional and Recreational Use (5)

Recreation uses including curling rinks, skating rinks, swimming pools and similar uses.

1 for each 50 square meters of gross floor area, plus .5 and for each spectator seat

Based on the preliminary program area of approximately 2,200 square meters for the proposed aquatic facility addition it was calculated that 44 additional parking spaces would be required. There has been discussion of moving the Library. Should the Library be relocate off-site as part of this project it might be reasonable to calculate a reduction in the overall parking requirement. The following diagram estimates that additional on-site parking can be developed in the order of the required 44 spaces.

Comparisons to other municipalities are useful in evaluating these requirements.

The Banff Land Use Bylaw is generally consistent with Revelstoke except that it requires 1 parking space per 50 square meters of gross floor area used by patrons. We estimate that this represents a 20% reduction in the total number of parking spaces or approx. 36 required parking spaces.
The City of Kimberley By-law has a requirement of 1 parking space for each 4 square meters of pool surface. This approach would result in a total 625 sq.m./4 = 156 required parking spaces. This calculation appears flawed and is untested.
The Vancouver Parking By-law has a requirement of 1 parking space for each 9.3 square meters of pool surface or surface used for assembly purposes. This approach would result in a total of 625 sq.m./9.3 = 67 required parking spaces.

The Revelstoke bylaw requirements appear generally consistent with these other precedents. Based on this it appears reasonable and practical to comply with the by-law.

Traffic patterns and the changes proposed in each of the Concept Options have not been specially addressed by the scope of this study, however, they may warrant specialized consideration by professional traffic engineers.

Geotechnical Report

Golder Associates has carried out a geotechnical feasibility study in support of the conceptual design for the proposed aquatic centre. The purpose of the investigation was to determine near surface soil and groundwater conditions. Generally, the results of this preliminary investigation indicate that the site is underlain by significant layers of loose fill containing organic material and construction debris to depths of 4.4 meters. Significantly this means foundations for the proposed aquatic centre need to penetrate this fill material to be founded on native sand/sand and gravel. Based on this supplementary analysis was carried out to establish a minimum set back from the bank and investigate the solid in relation to the proposed options. Ultimately this issue had a significant impact on the final site location.

Civil Engineering Review

Watson Engineering Ltd. has undertaken a review of civil and site service issues that can be determined in support of the conceptual design for the proposed aquatic centre. It is anticipated that through investigations of existing city services in the vicinity of the site that appropriate costs and scope can be determined as they affect the feasibility of the project.

Generally speaking, adequate capacity is present in the existing services at or near the proposed aquatic centre addition.

The 16" diameter sanitary sewer gravity main that exists along the westerly edge will have to be partly relocated with all the Concept Options except that in Concept Option 1 may have the least impact as it remains the farthest back from the river bank and sanitary sewer line. Further investigation is taking place into the scope of the service relocation required and will be developed in conjunction with the Preferred Option.

Structural Engineering Review

Triggs Engineering Ltd. has undertaken a review of proposed Facility relative to the geotechnical report. This valuable advice helped to defined the foundation costs used in the construction cost estimate.

Building Code Review

The Project consists of a swimming pool addition to an existing community centre. Ancillary spaces such as change rooms, mechanical rooms and lobby will be included in expansion.

Building Type Category - A2

OPTION 2

provide firewall to new construction- includes parapets.
provide fire shutters where circulation is tied in to existing
New pool would be governed under 3.2.2.30 - A3
Combustible or non-combustible construction for pool building
can delete sprinklers to both buildings
upgrades to existing community centre would have to be negotiated with AHJ in Revelstoke

*Locations be confirmed at DD stage. Shared Lobby condition would have to be reviewed for exit through lobby conditions. Existing exiting will have to be reviewed once door widths and existing room areas are known.

**Note that Occupant Load can be determined by projected use load and not strictly floor space ratio and/or pool tank size . Owner to agree and signs will have to be posted to satisfaction of AHJ and Fire Dept. Affects WC count.

Also requiring confirmation:

location of fire hydrants
Bleacher design and capacity (if any)
municipal water pressure for sprinklers j. Washroom count
seismic upgrade to code - existing building k. Fire truck access route design and
